Final answer:
The Installation RSO holds the overall responsibility for an installation's radiation protection program, managing safety protocols and ensuring compliance with regulations.
Step-by-step explanation:
The overall responsibility for the installation's radiation protection program lies with the Installation Radiation Safety Officer (RSO). The Installation RSO is tasked with overseeing the development and implementation of all aspects of the radiation protection program, which can include ensuring compliance with regulations, training personnel on radiation safety, managing radioactive materials, and maintaining the necessary documentation. This individual is usually backed by a radiation safety committee or board, but the primary responsibility for the program's operation and effectiveness rests with the Installation RSO, not the radioisotope committee, Permit RSO, or inspector general.
